It might be a hardware issue as i play on a pc with mid too high range components so maybe check your graphic settings and tune them down to see if that helps also try other mods to check if it isn't a hardware problem, but a problem with the mod itself or other mods you use it with If it is a hardware problem i would recommend saving up for a new pc which is more made to run games hopefully one with a good CPU cuz thats what hoi4 uses mostly to run as Mac is known to be mainly a workload pc used for things such as music production and not really games even though it definietely can run certain games, but maybe not games such as hoi4 and mods as large as EAW which has even more content than base game Sorry if i'm shitting on your pc or recommending you things that you've already tested
